Title: Deflection detector for conductor
Inventor: FUCHITA TAKASHI
IPC: G01B7/06
Filed: 1984-04-27
Abstract: PURPOSE:To enable a highly accurate detection with reduction in the effect of adjacent coils by shifting the phase of the resonance frequency of the adjacent detection coils to pick up outputs of the coils in terms of time. CONSTITUTION:Detection coils 41 and 42 are mounted at the lower part of the free end tips of conductive plate springs 31 and 32 fixed at one end thereof at a specified gap G. Since wave oscillators 111 and 112 and capacitors 121 and 122 are incorporated into a circuit of the coils 41 and 42 as resonance elements. The oscillators 111 and 112 are different in the transmission frequency. Then, when an object to be inspected is measured, according to variations in the gap G, changes in the eddy current between the coil 41 and the place spring 31 is detected as changes due to loss of the eddy current with the coil 41. But when the coils 41 and 42 approach each other interference tends to occur due to each other's magnetic fields. To lessen this tendency, in this apparatus, the oscillators 111 and 112 different in the oscillation frequency from each other are connected to the detection coils 41 and 42. This can reduce effects of noises of the coils 41 and 42.

Title: Image display method and device thereof
Inventor: AZUMA TAKEO
IPC: H04N5/57
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To improve contrast by a less circuit scale and an arithmetic amount, without being affected by a non-image part boundary around images and without causing a relative contrast decline at an image center part by increasing the weighting coefficient at the center of the images and reducing the weighting coefficient at a peripheral part for the count of a luminance frequency. SOLUTION: A delay circuit 3 holds input luminance for a fixed time and outputs the input luminance after a delay time, corresponding to the delay time by an optical illusion waveform generation circuit 2. A gradation conversion table calculation circuit 5 counts a luminance frequency for a representative area about a pixel, of which the absolute value of the output of an edge extraction circuit 4 is more than a threshold. For the count of the luminance frequency, the weighting coefficient is increased at the center of the images, and the weighting coefficient is reduced at the peripheral part.  By setting the representative area away from the end part of the images, a boundary with a non- image part is outputted as an edge, the luminance frequency of an image end part strongly affects the gradation converted result of the image center part, and the contrast is prevented from being lowered relatively at the image center part.

Title: Bipolar transistor
Inventor: TAWARA YOSHITAKA
IPC: H01L21/331
Filed: 1979-07-04
Abstract: PURPOSE:To increase the dielectric strength and current amplification factor of bipolar transistors by decreasing the dependence of breakdown voltage across collector and emitter upon the current amplification factor wherein the dependence of the current amplification factor upon the collector is also reduced. CONSTITUTION:P<+>-type gate layers 3 are buried in latticed shape in an N<-> epitaxial layer 4 on an N-type substrate 1 to form P<+>-type lead layers 3a, 3b. A base 5 and an emitter 6 are provided by double diffusion to install electrodes. A base electrode B and the gates 3 are connected. The impurity concentration of a collector 4 is generally smaller than that of the base 5 and if the concentration of the gates 3 is selected higher than that of the collector 4, a depletion layer from the gates 3 and base 5 continues to generate a small electric field in the direction of A. Therefore, collision energy with the atom of carriers from the base will not increase and an avalanche phenomenon will not occur. Accordingly, undesired dependence becomes small and an enhancement in collector voltage is made possible due to the above fact, while hFE will be increased.

Title: Gas burner
Inventor: MORI KEIICHI
IPC: F23N1/00
Filed: 1982-05-19
Abstract: PURPOSE:To control a gas flow rate by sensing gas pressure by a gas pressure sensor, converting it to a current value by an electronic circuit, and driving a valve body with electromagnetic force. CONSTITUTION:A valve body 23 is forced down onto a valve seat 22 by plate springs 29, 30 and cuts out gas even in case of power failure. An electronic circuit 33 compares the pressure detected by a pressure sensor 31 with the set pressure and reduces the current of an electromagnetic coil 26 if said detected pressure is higher than the set one to reduce electromagnetic force, and thus the valve body 23 is pushed back to the valve seat 22 by the plate springs 29, 30 and stops at a point where they balance with each other. On the contrary, if the detected pressure is lower, the valve body 23 is opened, allowing more gas to flow. Accordingly, if the original gas pressure varies to increase the gas pressure in an inlet chamber 20, a volume of gas flowing through a valve gap increases and the pressure in an outlet chamber 21 also rises, so that the control circuit 33 operates so as to throttle a space between the valve body 23 and the vlave seat 22, allowing the pressure in the outlet chamber 21 to return to the original one.
